Méthodologie des essais cliniques de petits effectifs

Abstract: RésuméLes essais cliniques de petits effectifs sont les essais dont le nombre de patients ne permet pas de répondre de manière correcte à l'objectif d'une étude avec les règles méthodologiques communément appliquées. Cette situation est fréquente dans le cas de maladies rares, en pédiatrie, dans certaines pathologies cancérologiques ou lorsque l'on souhaite limiter le nombre de patients exposés au traitement. Après avoir identifié les principaux problèmes méthodologiques, sont abordées les méthodes classiques … Show more

“…The over-arching theme was the consideration of pediatric age during the design, conduct and reporting of pediatric relevant trials. The age(s) of the participating children affects all aspects of a trial, including choice of intervention and comparator, selection and measurement of relevant and valid outcomes, expected treatment effect, differences in risk/benefit profile, effects on growth and development and disease processes [ 21 , 34 , 48 , 50 65 ]. Therefore, the detailed reporting of the age distribution of children in a trial is essential for the assessment of the appropriateness of age groups selected, the interventions, and outcomes, and the potential effects on growth and development.…”

“…Valid patient reported outcomes for adults may not be valid for young children [ 102 104 , 112 ], proxy reports may differ from child experience [ 102 , 112 116 ], symptoms in children may differ from those in adults, and what is considered healthy may differ between adults and children [ 21 , 61 , 106 , 107 , 117 122 ]. Also, due to these changes in outcomes measurement, validity of outcomes, and adverse impacts of treatment on the developmental trajectory of pediatric participants over time, the reporting of long-term monitoring of outcomes was also recommended [ 29 , 34 , 50 , 123 131 ].

“…Le choix de ce protocole sous forme d'étude croisée a révélé l'effet du traitement pFSH et de la race et ainsi d'accroître le potentiel de notre étude. En effet, ce type de méthode où chaque brebis est son propre témoin permet de réduire le nombre de sujets nécessaires (essais de petits effectifs), d'améliorer la fiabilité des résultats et est particulièrement indiqué si la variabilité de la réponse interindividuelle est importante (Vray et al, 2004).…”
